Definitions
- the invention relates to an implant arrangement according to the preamble of claim 1 , a crown according to the preamble of claim 19 , a tooth replacement part according to the preamble of claim 20 , a spreading instrument according to the preamble of claim 21 and a notching or separating instrument according to the preamble of Claim 25 .
- Dental prostheses with implant arrangements of this type are also under the name Known dental implants; this term is inaccurate because not everyone Part of such a so-called dental implant is actually direct is implanted; only one component is implanted, namely the most proximal one which the remaining components are attached directly or indirectly.
- Conventional tooth replacement parts usually consist of a crown, which essentially forms the visible part of the denture part, and from a base with a crown holder to which the crown is attached.
- the base will be generally through an implant arrangement and an adapter part that occasionally is also referred to as an abutment.
- the implant arrangement is the only part of the denture part implanted in the true sense of the word.
- the implant arrangement is implanted in a patient's jawbone, mostly screwed in.
- the adapter part is at the distal end of the implant arrangement attached and has the crown receptacle.
- the one on the crown admission the crown attached to the adapter part can be in one or more parts; for example, it can consist of a so-called framework and a veneer consist.
- a tooth replacement part of this type is used to replace a single tooth.
- Tooth there are also known dental prosthesis parts with which several neighboring ones Teeth can be replaced.
- Such tooth replacement parts generally include but not necessarily a second base, and the crown is as a bridge or Crown block trained.
- the first step is usually to build up bones.
- Many dental prostheses will be needed for patients who not only have bad teeth but also suffer from gum and jaw bone loss. This often applies to older ones Patients too. Younger patients or patients without gums and Dental bone parts usually only need to be replaced after an accident; however, the jawbone can also be traumatized. Lies a If there is a deficit in the jawbone, traditionally a bone build-up first be made. This is done before implanting the implant arrangement either an artificial substitute is attached to the jawbone, which is connected with the creation of an operating trauma in the jaw area, or it becomes natural bone mass, for example from the neighboring one Jaw area or from the pelvic area, implanted with the generation connected by two surgical trauma, in the pelvic area and in the jaw area is.
- the implantation usually takes place referred to as an implant post implant arrangement instead.
- the implant post takes a certain amount of time to complete in the required manner Waxing jawbones or, better said, waxing jawbones to become. Only then can the adapter part be attached.
- distal and proximal in the present description in the same sense as in general medicine be used; 'distal' and 'proximal' are relative terms, with 'distal' Parts further away from the center of the body and referred to as 'proximal' parts closer to the body center become.
- the terms 'distal' and 'proximal' here not only for body parts but also used for the dental prosthetic items, and they are not used for that either implanted definitive and temporary components of the dental prosthesis used, where 'distal' and 'proximal' refer to the layers that make up the components In the assembled state, take it permanently or temporarily in the patient's jaw.
- the terms 'proximal' and 'distal' also apply to the instruments or their arrangement used in use, with their Help the new implant element can be assembled.
- the implant arrangement according to the invention has a first, after implanting proximal implant element and a second, after Implant the distal implant element.
- the proximal implant element is attached in a proximal jaw bone area or deep screwed.
- the distal implant element becomes essentially coaxial and adjacent to the proximal implant element, in a distal area of the jawbone attached or screwed in less deeply than the proximal Implant element.
- the jawbone is between the proximal and distal jawbone areas at least partially separated or scored. Therefor special measures are taken, which are described in detail below are.
- This is followed by manipulation of the implant elements a displacement of the distal area of the jawbone in the distal direction from proximal jaw bone area away; this process is called distraction.
- the distraction takes place with further separation of the already partially separated or scored jaw bone.
- That gap gradually fills with natural, newly formed bone material.
- the additional bone material for a bone structure which in a conventional artificial bone surgery has been attached to the distal end of the jawbone, with the new one Process naturally in the gap between the proximal and distal Jaw area attached. It is known to any person skilled in the art that education of bone material in crevices is going particularly well, and that certain Gap widths and a certain amount of mechanical tensile stress are optimal for the formation of bone material; the gap between the proximal and distal jawbone area and if possible also the Stresses are chosen accordingly.
- the new implant arrangement shows numerous advantages. The most important of these advantages lies in that only one invasive procedure is necessary, so that all dangers and inconvenience of operations can be greatly reduced.
- the Dental prosthesis is completely assembled in a shorter time. The bone structure happens naturally and to a certain extent in situ.
- the entire proximal implant element and the entire preferably form distal implant element definitive components of the dental prosthesis to be created.
- Tensile stress means are used, which preferably also components of the implant arrangement and that are the function of tools take.
- the means for moving the distal jawbone area by manipulation the proximal and distal implant elements consist of at least an auxiliary element of the implant arrangement.
- This auxiliary element comes with connected to the distal implant element, preferably by means of a screw connection.
- the auxiliary element fulfills the functions of a tension member and an actuator.
- the auxiliary element with the distal end of the distal implant element screwed as far as possible. If the rotation continues of the auxiliary element, the distal implant element would then be taken along also screwed in deeper.
- the distal implant element is already like this screwed as deep as possible into the distal area of the jawbone, namely up to to the stop on the proximal implant element, and can be rotated further not be screwed in deeper.
- the further rotation of the auxiliary element therefore causes distraction of the distal area of the jawbone in the distal area Direction, or in other words, the displacement of the distal Jawbone area away from the proximal jawbone area.
- the auxiliary element generally has a proximal threaded section, which is screwed to a distal threaded section of the distal implant element becomes. It has proven to be particularly favorable to use the auxiliary element in the manner of a sleeve form, so that its thread section mentioned an internal thread contains while the complementary thread of the distal implant element is an external thread. The reverse arrangement of the threads or another Connection type is also possible.
- the means for moving the distal implant element the mentioned Auxiliary element and a further auxiliary element, the first auxiliary element being the Function of a tension element and the further auxiliary element the function of an actuator Has.
- the auxiliary elements are relative in the direction of the longitudinal axis of the implant movable with respect to one another and in terms of movement with the implant elements coupled such that the distal implant element with the first auxiliary element and the proximal implant element in solidarity with the further auxiliary element is movable.
- the other auxiliary element designed as an actuator is like this adjustable that when it is adjusted, a relative shift between the Auxiliary elements in the direction of the longitudinal axis of the implant takes place.
- This relative shift of the auxiliary elements causes a simultaneous relative shift of the implant elements. Because the proximal implant element essentially is firmly anchored in the proximal jawbone area and cannot be moved, the relative displacement of the implant elements manifests itself in a distraction of the distal implant element in the distal direction.
- the auxiliary element that is used as a tension member, sleeve-like, that is, designed as a tension sleeve his.
- the second auxiliary element which is used as an actuator, can be used as an adjusting screw be trained.
- the tension sleeve and set screw are connected to each other that they have a relative displacement in the direction of the longitudinal axis of the implant can perform.
- the other auxiliary element, the actuator is formed can have a thread and an active surface; this thread the further auxiliary element is with a complementary thread of the former Auxiliary element adjustable screwed, so that a threaded connection is formed; the effective area of the actuator, that is, furthermore Auxiliary element, lies on a pressure surface of the proximal implant element on.
- the actuator is rotated, i.e. the threaded connection is attracted; the active surface of the actuator is supported here this pressure surface and is on the pressure surface of the proximal implant element biased.
- Tightening the threaded connection therefore has the consequence that the first auxiliary element, that is the tension member, extends in the distal direction moves and takes the distal implant element with it, the latter in turn takes the distal area of the jawbone with it and the proximal area Jawbone area removed.
- the distal implant element is advantageous screwed back in until it lies against the proximal implant element, because this will make the two definitive components of the implant arrangement into one more stable location.
- dental prosthesis parts from an implant arrangement a crown receptacle and a crown.
- the crown admission is conventionally formed on an adapter part, which in the assembled Condition of the tooth replacement part between the crown and the implant arrangement is arranged.
- the new implant arrangement is designed so that the adapter part is unnecessary.
- an integral crown mount is made on one of the implant elements formed so that the crown attaches directly to the implant element can be.
- the crown admission can be arranged either on the proximal or on the distal implant element.
- a crown fixation on the proximal implant element can lead to a more stable one Fix the crown fixation.
- the assembly of the crown is made easier if the crown admission is at the most distal area of the implant arrangement is provided; but this is not mandatory, because a crown with A suitable, sufficiently large recess need not be at the most distal area be attached to the implant arrangement.
- the proximal implant element has an approach, the distal end of which projects beyond the distal implant element in the distal direction and is designed as a crown receptacle. With this arrangement you can achieve both a stable attachment of the implant arrangement in the jawbone as also an easy assembly of the crown.
- crown receptacle with an external thread, so that there is a crown with a complementary internal thread the approach can be screwed on.
- a dental prosthesis Because micro movements between the various definitive components of a Dental prosthesis for injuries to the adjacent living jaw area can lead, these components are preferably designed and arranged that they are firmly assembled in the assembled state or are tied together.
- Definitive components of a dental prosthesis are at least the proximal implant element, the distal implant element and the crown.
- a tight arrangement of the definitive components of the denture part is obtained by placing a tendon on an approach of the proximal Fixed implant element, preferably screwed, and this distal implant element between the tendon and the proximal implant element clamps.
- Tension member has a tensile force on the proximal implant element and a compressive force on the distal implant element lying against the proximal implant element out.
- the assembled tendon is then covered by the crown, that is, it is in the assembled state of the dental prosthetic item Recess of the crown.
- the crown can be glued or cemented, for example be attached.
- the crown can also be made of one material be produced that is not suitable for a screw connection.
- the crown also takes on the function the tendon; for this purpose it has an internal thread with which it has the proximal implant element is screwed on.
- the aim should be both implant elements and the means are designed to move the distal implant element so that the Implant arrangement sealingly arranged on the jawbone and in the gums can be used to prevent the entry of microorganisms or foreign bodies.
- the means for moving the distal jawbone area be designed so that they have a sealing effect.
- the auxiliary element designed as a tension sleeve can have a tapering surface, those in the assembled state tired of a complementary conical surface of the distal implant element comes into contact. This further points out
- Auxiliary element preferably has a sealing end in its distal end region on.
- auxiliary element that as a train and as Actuator acts, for example, a closed at the distal end Cable sleeve can be used.
- two auxiliary elements namely a tension member in Form of a pull sleeve and an actuator in the form of an adjusting screw, see above an intermediate element is preferably provided, which by a suitable, e.g. elastic, sealing element is formed and the connection point seals between tension sleeve and set screw.
- the implant elements are preferably designed in such a way that they are mounted in the corresponding jaw bone area by screwing in.
- they have a section with an external thread.
- a particularly suitable external thread is described in EP-1 112 722-A2 . It is a self-tapping thread. This has the advantage that the pre-drilling and tapping processes are eliminated and there are no centering problems when screwing in the implant element.
- the invention is not only concerned with the two-part implant arrangement described above but also with two instruments, which are used to assemble the Implant arrangement can be used and this assembly considerably easier.
- proximal implant element in the existing or previously built Implanted jawbone.
- proximal implant elements are preferred by screwing in so deep in a proximal jawbone area attached that their proximal ends generally in those of those Teeth come to rest, which must be replaced by a dental prosthesis. It is assumed here that the implant arrangement used the distal end of the proximal implant element after implantation out of the jawbone and the adjacent gums protrudes.
- the distal implant element is implanted, adjacent to the proximal implant element in a distal area of the jawbone. After that the means for distracting the distal area of the jawbone are attached.
- special measures can be taken for this for which the instruments described below, namely a Spreading instrument and a notching or separating instrument are used, which are described below.
- a spreading instrument in particular the spreading instrument according to the invention, is used to extend the jawbone over a height range in which it is a has thin walls to spread.
- This height range corresponds to Generally around the distal area of the jawbone.
- Spreading the distal Jawbone area is preferably done after implantation of the proximal implant element, but before the implantation of the distal implant element.
- the gums are placed in the surgically opened to the appropriate height and held away from the jawbone.
- the proximal implant element is mounted or screwed in. There is generally a pilot hole or cavity for this of the jawbone is necessary, but it has only a small diameter on.
- the above-mentioned spreading of the jawbone takes place, the cavity being spread around the proximal implant element and this creates a space for the insertion of the distal implant element becomes. Thanks to the spreading, it is not necessary in the high range the spread, where there is little bone material, a pre-drilling with a relatively large diameter in which the distal implant element can be screwed in. This will prevent this Height range in which only a very small amount of bone material is present, part of this bone material is removed by drilling. The bone material that is still present can thus be preserved almost completely become. This gives the advantage that bone material is preserved in one place where it is not or only to a very limited extent newly formed could.
- a notching or separating instrument is used for the following purpose: After installing the implant arrangement in the jawbone there will be a gap of the gums from the jawbone, which is caused by holding the Gums were created from the jawbone. In this distance between the jawbone and the surrounding gums can now be scored Separation instrument can be introduced. By means of the notch or Separating instrument is then made a notch or joint on the jawbone at least in an intended bone separation plane.
- the Bone separation plane is essentially defined by the position of the contact plane, in which the proximal implant element the distal implant element touched.
- the gums are like already mentioned, not surgically removed but only opened surgically and kept away from the jawbone.
- the notching or separating instrument is inserted up to the bone separation level, with the gums if necessary can be cut. Then the jawbone is in the bone parting plane scratched with the help of the notching or separating instrument or notched. Complete separation of the distal area of the jawbone from the proximal jawbone area then takes place in the Course of distraction of the distal area of the jawbone as above is described. If the jaw bone was only scored, the notch deepens of the bone separation area to form a parting line, which then connects expanded to a crack. This gap forms, as also above described, natural bone material.
- the temporary components of the implant arrangement can then from the definitive components of the implant arrangement be removed, and on the definitive components of the implant assembly is then either an adapter part with a crown mount or preferably attached to the crown itself.
- the spreading instrument has an expansion sleeve with a Recess on and is over the distal approach of the proximal implant element pushed.
- the expansion sleeve runs outside through the expansion surface, for example conical, limited.
- the expansion sleeve is easy to spread in the proximal direction over the attachment of the proximal implant element slipped on one shoulder of the same.
- the expansion sleeve is in use distal end attached to a handle part.
- two of the spreading surface can be at least approximately diametrical arranged blades protrude outwards.
- the cutting edges can be in cross section seen at an angle so they are in use run approximately tangentially in the direction of the arch of the jawbone.
- the Can use a distal area in use, in which their cutting edges parallel to the axis of the recess and thus parallel to when in use Longitudinal implant axis run.
- At this distal area of the Cutting edges can join a proximal area of the cutting edges when in use, in which the cutting edges taper in the proximal direction; such a tapering area facilitates the introduction of the spreading instrument.
- two clean cuts are made, which are the spreading facilitate and prevent violent violence, but then again overgrown.
- the spreading area is the Spreading sleeve divided into segments.
- the segments are in the rest position the spreading surface parallel and adjacent to the approach of the proximal implant element. In the active position, the segments are at least partially respectively spatially spaced from this approach and thus spread the jawbone away from this approach.
- Spreading instruments can also be used if necessary to advance screwing the proximal implant element into the proximal jawbone area to spread after creating a small diameter hole has been; this reduces the amount of bone material that passes through Drilling is destroyed and lost.
- Notching or separating instruments used when implanting implant arrangements can be used for dental prostheses can be designed differently his.
- a preferred notching or separating instrument is according to the Invention is designed as pliers.
- the pliers can be different, for example have interchangeable inserts, in particular a notch insert and one Cutting insert.
- the new notching or separating instrument preferably has one Device which allows the notching or cutting inserts in Direction of the longitudinal axis of the implant or in terms of height in the bone separation plane to position

- the effective area of the adjusting screw 16 acts via the intermediate member 19, the printing surface of the proximal implant element 12th Since the proximal implant element 12 cannot be moved further in the proximal direction despite this pressure, tightening the set screw 18 causes the pulling sleeve 16 to move in the distal direction, thereby taking the distal implant element 14 and the distal jaw bone region 44 with it.
- the distal implant element 14 is displaced, it is guided on the proximal implant element 12 remaining stationary in the proximal jaw region 42 .
- FIG. 4E shows this process in a state in which the gap 43 is approximately half its final size Has reached width. Natural bone material gradually forms in the gap 43 ; In this way, bone build-up or replacement of the bone material lost due to bone loss occurs.
- FIG. 4F shows the final state of the distraction of the distal jaw bone region 44 described above; This was displaced so far in the distal direction by the distal implant element 14 anchored in it that - together with the bone material newly formed in the gap 43 - a jawbone was created which roughly corresponds to the original jawbone according to the dashed line 41 in FIG. 4A equivalent.
- the final width of the gap 43 or the thickness of the new bone material can be approximately in the range from approximately 0.5 mm to approximately 5 mm.
- 4G finally shows the distal implant element 14 screwed back up to the shoulder of the proximal implant element 12 after distraction of the distal jaw bone region 44 .
- Fig.4G shows a state in which the temporary components of the Impantat assembly 10, 10 from the definitive components of the implant assembly.
- the proximal implant element 12 and the distal implant element 14 remain definitely implanted.
- the auxiliary element, ie the pull sleeve 16 including the intermediate element 19 arranged therein and the further auxiliary element, namely the set screw 18, are removed.
- Temporary components of the implant arrangement 10 can generally be loosened gently using ultrasound.
- the crown 50 is fastened on the distal end region or crown carrier 12.4 of the proximal implant element 12 , which is designed as a crown receptacle , in the same way as described above with reference to FIG. 2G .
- FIG. 5 shows a section of a tooth replacement part 1 with a crown 50 which is fastened on the crown carrier 12.4 of the proximal implant element 12 .
- FIGS. 6A to 6C show a first embodiment of the spreading instrument 60 according to the invention.
- the spreading instrument 60 is used, in particular, to spread a small-diameter bore or cavity in the jawbone 40.1 so that there is a distance surrounding the attachment of the proximal implant element 12 , so that the distal implant element 14 can be screwed in.
- the gums 40.2 are opened surgically beforehand and kept away from the jaw bones 40.1 .
- the spreading instrument 60 essentially consists of a handle 61 and an expansion sleeve 62 attached to this handle 61 .
- the expansion sleeve 62 has a recess 64 running in the direction of the longitudinal axis of the sleeve, which is designed to be complementary in cross section to a sleeve guide part of the implant element 12 .
- the sleeve guide part is formed by the attachment of the implant element 12 , which is located in the small-diameter bore or hollow in the distal jaw bone region 44 .
- the expansion sleeve 62 is delimited on the outside by an expansion surface 66 , which is preferably designed to taper in the proximal direction.
- the spreading instrument 60 For spreading the jawbone 40.1 respectively of the distal jawbone zone 44, starting from extension of the proximal implant element 12, the spreading instrument 60 is manipulated such that the spreader is moved from a rest position to an operative position 66, either by slight rotation or displacement in the direction the longitudinal axis of the implant. In the rest position of the expansion surface 66 , the expansion sleeve 60 rests with its recess on the shoulder or sleeve guide part of the proximal implant element 12 , but is still in the already existing cavity in the jaw bone 40.1 .
- the spreading surface 66 is gradually brought into its operative position by spreading the expansion sleeve 62 in the proximal direction away from the attachment or sleeve guide part and thereby essentially spreading the distal jawbone region 44 .
- the displacement of the expansion sleeve 62 ends when its front surface 63 comes to abut against the shoulder of the implant element 12 , which borders on the implant thread of the implant element 12 .
- the expansion surface 66 of the expansion sleeve 62 preferably has cutting edges 68 projecting radially outwards. Such cutting edges 68 extend at least over part of the height of the expansion sleeve 62 and are preferably designed to taper in the proximal direction at least at their proximal end region 69 . In general, two such cutting edges 68 are arranged, which are arranged at least approximately diametrically. Expansion sleeves 62 with cutting edges 68 are preferably brought into their operative position only in a straight line.
- the spreading surface 66 is in this case formed by spreading segments 67 which, for example, run in a rest position in the direction of the longitudinal axis A of the implant and are then adjusted to the outside into a working position in which the jawbone 40.1 is spread.
- the spreading segments 67 can be moved mechanically or fluid-operated.
- FIG. 7A shows the notching or separating instrument 70 according to the invention. These are pliers with two jaws 72 . A pair of pliers with several circumferentially distributed jaws could also be used.
- a second pair of inserts 76.1 76.2, which is shown in FIG. 7C serves to separate or cut the jaw bone 40.1 laterally and in the direction of the bone separation plane S.
- a device 78 in the manner of a spacer sleeve, shown in FIG. 7A, serves to position the inserts precisely, so that the notching or cutting takes place at the intended locations.
- the materials for the implant elements 12 and 14 are used as materials for the implant elements 12 and 14 .
- the materials for the auxiliary element 16 and, if appropriate, the further auxiliary element 18 must have sufficient mechanical strength and can be combined in threaded connections with the materials of the implant elements, but the demands regarding long-term biocompatibility are lower; generally titanium or chrome alloys or chrome steels are used.
- the intermediate element 19 which is used in the present second exemplary embodiment, consists of a suitable plastic that has been tested for such purposes, for example of polyethylene.
- implant arrangements 10 described above are only to be regarded as examples. Numerous other configurations of the implant arrangement 10 according to the invention are possible within the scope of the patent claims. It is thus possible in particular to create implant arrangements in which the layers of internal and external threads and / or internal and external or sleeve-like and core-like elements are interchanged with respect to the above exemplary embodiment; Furthermore, the crown carrier can be attached to the distal implant element or a conventional additional adapter part can be used to attach the crown.
